Sura Āl-ʿImrān 3:20

فَإِنْ حَآجُّوكَ فَقُلْ أَسْلَمْتُ وَجْهِىَ لِلَّـهِ وَمَنِ ٱتَّبَعَنِ وَقُل لِّلَّذِينَ أُوتُوا۟ ٱلْكِتَٰبَ وَٱلْأُمِّيِّۦنَ ءَأَسْلَمْتُمْ فَإِنْ أَسْلَمُوا۟ فَقَدِ ٱهْتَدَوا۟ وَّإِن تَوَلَّوْا۟ فَإِنَّمَا عَلَيْكَ ٱلْبَلَٰغُ وَٱللَّـهُ بَصِيرٌۢ بِٱلْعِبَادِ

fa-in ḥājjūka fa-qul aslamtu wajhiya lillāhi wa-mani ittabaʿani wa-qul li-lladhīna ūtū l-kitāba wa-l-ummīyina a-aslamtum fa-in aslamū fa-qadi ihtadaw wa-in tawallaw fa-innamā ʿalayka l-balāghu wallāhu baṣīrun bil-ʿibādi

So if they dispute with thee, say: "I have submitted My whole self to Allah and so have those who follow me." And say to the People of the Book and to those who are unlearned: "Do ye (also) submit yourselves?" If they do, they are in right guidance, but if they turn back, Thy duty is to convey the Message; and in Allah's sight are (all) His servants.
